Definitions

  • the invention relates to a device for the mechanical separation of individual parts of different shape and size, for example for sorting out injection molded parts and sprue, consisting of a rotatably mounted cage, the lateral surface of which is composed of longitudinal rods arranged at a distance from one another, the individual longitudinal rods of which can have any geometric shape and in the form of movable jacket rods in two side rings on the two end faces, wherein they rotate opposite to the direction of rotation of the inclined cage and open on both end faces.
  • the sieve drums used for this purpose consist of a rotatably mounted cage, which is open on both ends, the outer surface of which is composed of longitudinal rods arranged at a distance from one another.
  • the free passage between the longitudinal bars is adjusted by hand to the size of the material to be separated for each longitudinal bar.
  • the object of the invention is to arrange the longitudinal bars of the lateral surface in the side rings so that the setting of any distance between the longitudinal bars can be carried out easily and quickly.
  • the object is achieved in that a plurality of longitudinal rods fixedly distributed on the circumference in the round blank are connected to one another via a non-positive adjustment drive, preferably a chain.
  • the invention is characterized in such a way that the movable longitudinal bars are guided and connected via a planetary plate to the longitudinal bars fixed in the round blank.
  • the movable longitudinal bars are non-positively connected to the fixed longitudinal bars via radial guides in the round blank.
  • the invention is further characterized in that the circular blank has undulating recesses on the outlet side of the separating drum.
  • the movable longitudinal bars are arranged inside or outside the cage and the fixedly mounted longitudinal bars.
  • Another feature of the invention is the fact that a fixed longitudinal rod and a movable longitudinal rod are non-positively connected to one another via a drive element, preferably a rubber ring.
  • the fixed longitudinal rod can have any geometrical shape in cross section.
  • the fixed longitudinal rod is wrapped in a movable counter rod, the movable counter rod being non-positively connected to the adjustment drive.
  • a guide ring (2) is embedded in the round blank (1) and firmly connected to the round blank (1) by means of a screw (3).
  • a chain sprocket (4) is rotatably mounted in the guide ring (2).
  • the planet plate (6) is firmly connected to the chain sprocket (4) via a connecting element (8).
  • the fixed longitudinal rod (5) is rotatably connected to the shaft (11) by means of a pipe section (10) and a bearing (9).
  • the shaft (11), the planet plate (6) and the chain sprocket (4) are firmly connected to each other by means of a screw (7). With this arrangement it is possible that the longitudinal bars (5) can rotate freely and the chain sprocket (4) with the planetary plate (6) are fixed.
  • the longitudinal bars (5) with the chain sprockets (4) located outside the separating drum are fixed in the blank (1) and are non-positively connected to each other by an endless chain (12).
  • the endless chain (12) it is also possible to use a toothed belt, cable pull or parallel linkage or a ring gear with internal or external teeth or any other non-positive connection.
  • the advantage of the chain is u. a. in that you can make a fine adjustment of the entire adjustment drive with tensioners, which are located between the fixed longitudinal rods.
  • the movable longitudinal bar (20) is arranged in the planetary plate (6) at a distance which corresponds at least to the radius of the fixedly mounted longitudinal bar (5) plus the radius of the movable longitudinal bar (20) plus an air gap.
  • the structure of the movable longitudinal rod (20) is identical to that of the fixed longitudinal rod (5).
  • the movable longitudinal bar (20) is fixed in the center with a screw (25) to the planetary plate (6).
  • the separating drum is driven by a non-illustrated drive unit (26) in a force-locking manner on a ring (13) which is firmly connected to the round blank (1) by means of screws (14).
  • Each longitudinal bar (5), (20) has a recess (16) in the pipe section (10).
  • An elastic ring (17) engages in the recess (15), which is attached to the frame, not shown, and causes all longitudinal rods to rotate in the opposite direction to the overall drum rotation when the separating drum rotates.
  • the elastic ring (17) Since when moving the movable longitudinal bars (20) into or out of the cage, the elastic ring (17) only detects the longitudinal bars that form the larger diameter of the cage and also drives them, each becoming a longitudinal bar of the larger cage diameter with a longitudinal rod of the smaller cage diameter on the elastic endless ring (18) non-positively connected. This arrangement ensures that all longitudinal bars (5), (20) rotate counter to the direction of rotation of the separating drum. As a result, the separation area of the drum is significantly expanded.
  • the overall construction makes it possible to set the distance between the longitudinal bars of the separating drum to a defined dimension by moving the endless chain (12) in one direction, whereby all the longitudinal bars in the cage can rotate.
  • FIG. 3 shows a further exemplary embodiment. It shows the adjustment of the movable longitudinal bars (20) in the radial direction.
  • Radial guides (21) are arranged in the round blank (1).
  • the movable longitudinal rods (20) move radially in these guides (21).
  • a shaft (27) with a double chain sprocket (5a) is rotatably arranged in the outer area of the round blank (1).
  • This adjusting device consisting of shaft (27), double chain sprocket (5a), chain (22) and endless chain (12) is assigned a movable longitudinal bar (20).
  • the double chain sprocket (5a) is designed such that a chain (22) running in a guide (21) is firmly connected to the center of the movable longitudinal bar (20) and to the second ring gear of the double chain sprocket (5a).
  • the chain (22) rolls up onto the second sprocket of the double chain sprocket (5a) and thus pulls the movable longitudinal bar (20) radially in the guide (21) the blank (1) to the outside.
  • the positive connection chain (22) and guide (21) can also be designed as a cable with spring, or as a linkage or the like.
  • the separation drum and the longitudinal bars are driven as previously described.
  • FIG. 4 shows a further embodiment. It shows the adjustment of the movable longitudinal bars (20) radially.
  • a radial guide (35) is provided in the blank (1).
  • a guide plate (23) is firmly connected to the fixed longitudinal rod (5).
  • the guide plate (23) also has a guide (28) in the axial direction of the longitudinal bars.
  • a sliding block (36) is fastened to the movable longitudinal bar (20) and is movably arranged in the guide (35) of the round blank (1) and further in the guide (28) of the guide plate (23).
  • all longitudinal bars are designed as fixed longitudinal bars (5), (37).
  • the fixed longitudinal rods (5), (37) preferably have a rectangular cross section. Any other geometric cross section is applicable.
  • the fulcrum for the various geometric shapes of the longitudinal bars can be located at any point in the cross section. A circular cross section of the longitudinal bars can thus also be used.
  • the fixed longitudinal rods (5), (37) are firmly connected to the chain sprocket (4) and mounted in the round blank (1).
  • the endless chain (12) moves, the chain sprockets (4) and thus the fixedly mounted longitudinal bar (5), (37) are rotated about their axis.
  • the gap (38) can thus be set quickly and precisely. The detection of this device can be done as previously described.
  • the fixed longitudinal rod (5) is firmly connected to the round blank (1).
  • a tangential guide (30) is arranged in the blank (1).
  • a guide element (39) is installed in this tangential guide (30) and is firmly connected to the endless chain (12) via a fastening plate (31).
  • the guide element (39) is firmly connected to the movable counter rod (29) via a fastening element (32).
  • the chain (12) is held by a sliding guide (33).
  • This construction ensures that the free passage between the longitudinal bars of the cage can be set to a defined level.
  • the round blank on the outlet side is cut out in a wave shape.
  • a correspondingly corrugated sheet (24) is arranged in this undulating recess. This corrugated sheet (24) is firmly connected to the guide ring (2) and protrudes beyond the drive device. As a result of this measure, no separated material can get into the drive device if it is located on the outlet side of the drum cage, which is open at the end.
  • the drive device for adjusting the distances between the longitudinal bars can be either on each end face of the cage or only on one side.
